Question

Assume you cross a pure plant that has the genotype GG with a pure pea plant that has the genotype gg. What are all of the possible genotypes of the offspring?

GG, Gg, and gg

Only GG

GG and gg

Only Gg

Answer 1

D. Only Gg

Step-by-step explanation:

We have a plant with genotype GG and another with genotype gg. We need to make a Punnett Square (see attachment). Basically, we're putting the two alleles of Parent 1 (G and G) at the columns and the two alleles of Parent 2 (g and g) at the rows. Then, we "cross" them.

Notice from the Punnett Square that the only possible genotype of the offspring is Gg. The answer is D.

Hope this helps!
